Xavier Diaz

I’m a software engineer who builds and ships production AI systems, pushing foundation models to their limits through prompting, evaluation, and infrastructure engineering. I take true end-to-end ownership, from architecting modular backends to shipping features that scale and stay reliable.

At Bank of America, I architected Python automation scripts that reduced manual reporting time by 30% and owned resolution of 1,800+ Jira tickets within a 12-month period while maintaining SLA compliance and detailed documentation. I’ve also participated in enterprise production deployments using Jenkins and Ansible Tower, following rigorous SDLC validation in a security-conscious financial environment.

In my engineering projects, I’ve built secure, modular AI agent platforms and real-time automation infrastructure—integrating LangChain and ChromaDB for contextual memory, implementing WebSocket-based communication, and designing multi-user authentication with encrypted session management. I thrive where creativity meets reliability, especially in high-volume, security-sensitive environments where uptime and quality are non-negotiable.
